Shulou(Shulou.com)11/24 Report--

There is a very interesting phenomenon in the first batch of RTX4070 cards released this year. The number of white-painted cards has greatly increased, and there is a great sense of design in the painting style and texture details, such as the Sotai RTX4070 X-GAMING OC Opal White we got. Of course, the dual Buff, which is known as low power consumption and low noise, is also the biggest selling point of this RTX4070, so let's borrow this card to see how RTX4070 performs.

In this test, CTOnews.com will be used as a test platform with the following hardware to ensure that there are no performance bottlenecks during the test.

Design Sotai RTX4070 X-GAMING OC Opal White is a two-and-a-half slot card, BWH size is 30.3x12.1x6.1cm, this size for the compatibility of the chassis is good, will not feel too heavy in the hand.

On the front of the graphics card, the external armor uses a lot of light gray graffiti texture, which looks very cool, but the low saturation tone with a pure white background will not appear too flamboyant.

The fan part of Sotai RTX4070 X-GAMING OC Opal White is also treated with all-white painting, including the transposable part, so the visual integrity of the whole graphics card is strong.

The backplane part of Sotai RTX4070 X-GAMING OC Opal White has more graffiti elements, and the hollowed-out area on the right side of the backplane is not large, but it can also help the cooling air blow through the fins and enhance the heat dissipation effect.

The outermost ring of the back panel of the video card is a white edge, and the ZOTAC letter logo in the middle supports RGB lighting. The default light is white and has a strong sense of integration. It also supports various mainstream lighting synchronization software and custom light effect adjustment.

The side interface part is equipped with 3*DP1.4 interface and 1*HDMI2.1 interface, supporting up to 8K / 60 frame output. In terms of power supply, it adopts the 16Pin power supply interface of the latest ATX3.0 specification, which is consistent with RTX4070Ti.

Like RTX4070Ti, the core of RTX4070 is built by ‏‏ based on AD10 ‏‏ 4 core. There are 4 groups of GPC full of blood in ‏‏. There are 5888 CUDA cores, 184‏‏ Tensor cores, 46 third-generation RT cores and 64 ROP unit ‏‏ in ‏‏ in ‏‏. In addition, NVENC video encoding unit is one less than 4070Ti, and NVDEC video decoding unit is still retained.

The ‏‏ core frequency of RTX4070 is 1920MHz, and the ‏‏ Boost frequency 2495MHz. In the aspect of ‏‏ video memory, the ‏‏ is a 12-‏‏ GB GDDR6X ‏‏ with 192 ‏‏-bit ‏‏ bit width, and the video memory frequency is as high as 21000MHz. From the above positioning, we can see that RTX 4070 is a high-end graphics card for positioning 2K high frame rate games.

RTX 4070 also builds ‏‏ based on the latest NVIDIA Ada architecture, and its ‏‏ is upgraded to ‏‏ TSMC 4N NVIDIA custom process, resulting in a leap in performance and power consumption of up to 2x. The ‏‏ throughput of streaming multiprocessor ‏‏ is twice as high as that of the previous generation. The effective ray tracing computing power of the third generation RT Cores is 2.8 times higher than that of the previous generation. The fourth generation of Tensor Cores adds a new FP8 engine with up to 1.32 petaflops of Tensor processing performance, which is five times higher than that of the previous generation. SER brings up to three times the performance improvement for RayTracing, and up to 25% improvement for overall game performance.

As for the concrete function, the new architecture brings a lot of new functions: due to the introduction of Ada optical flow accelerator, DLSS 3 can predict the motion changes between frames in the scene, realize AI frame insertion, and improve the frame rate while maintaining the image quality.

Theoretical performance next, we conduct a theoretical performance test, double baking for 15 minutes, when the core temperature of the graphics card is stable at 61 degrees and the power consumption is 204W. To tell you the truth, this temperature control is very good, after all, the power consumption is relatively high, and there is not much noise. The experience is a little unexpected.

Next, there is a 3DMark pressure test, which can detect whether the performance of the graphics card has declined under continuous running minutes. Generally, more than 97% can be regarded as a qualified graphics card. Sotai RTX4070 X-GAMING OC Opal White finally scored 99.2% and passed the test perfectly.

In the 3DMark TimeSpy DX12 test, Sotai RTX4070 X-GAMING OC Opal White got a graphics card score of 18137, slightly lower than the 18793 score of RTX 3080 12GB, while the RTX 3090 score of 20501 was considered a normal performance.

In the 3DMark Fire Strike Extreme test, Sotai RTX4070 X-GAMING OC Opal White's graphics card score ‏‏ is 21074, as a comparison, the GeForce RTX3080 12G score is ‏‏ 22781 ‏‏.

On the other hand, in the 3DMark Portal Royal light pursuit test of ‏‏, Sotai RTX4070 X-GAMING OC Opal White scored ‏‏ 11123 and ‏‏ RTX3080 12GB scored 12157. However, reflected in the actual game, the gap will not be too big.

Game measurement ‏ next, we will conduct a game test. We will test all games with the highest 2K resolution. If we have DLSS, we will enable the balance file DLSS, and if we have DLSS3, we will test the number of frames before and after opening and closing. First of all, the old FPS game "CS:GO", Sotai RTX4070 X-GAMING OC Opal White reached 480 frames, enough to play with a high-brush display.

It is worth mentioning that at present, eight of the top 10 competitive shooting games support NVIDIA Reflex, including "Apex Hero", "call of Duty: theater 2", "Destiny 2", "Escape from Takov", "Fortnite", "Watchman: return", "Rainbow 6: siege" and "Dauntless contract". Opening NVIDIA Reflex can help players ensure high picture quality and high frame rate at the same time. It can also have the lowest delay performance, which I will mention in more detail in later reviews.

We also tested two classic 3A games. In Tomb Raider: shadow, Sotai RTX4070 X-GAMING OC Opal runs its own benchmark with a 2K resolution and the default highest image quality, with an average frame count of 174. as a comparison, RTX3070Ti can run to 142. after opening the DLSS2 quality file, the frame count is increased to 207. as a comparison, RTX3070Ti is 165frame.

There is also a masterpiece, "the Wild Dart 2: redemption," in which the average frame with the highest 2K resolution is 103. as a contrast, the RTX3070Ti can run to 90 frames; when the DLSS quality file is turned on, it can also achieve an average score of 120 frames; as a comparison, RTX3070Ti can run to 90 frames, which can basically be said to be experienced at 2K.

Of course, all these frames are based on DLSS2, and the most attractive thing about the RTX40 series is DLSS 3 technology. ‏‏ DLSS 3 is a performance multiplier ‏‏ technology ‏‏ driven by AI, driven by the new fourth generation Tensor Core and the new optical flow accelerator of the GeForce RTX40 series GPU, the latest version of NVIDIA's acclaimed deep learning supersampling technology and groundbreaking optical multi-frame generation, which will usher in a new era of NVIDIA RTX neural network rendering games and applications.

To put it simply, in the past, DLSS 2 improved the image quality and the number of frames by rendering a low-resolution image, and then AI zoomed in to high resolution. While the new DLSS 3 is compatible with DLSS 2, it also adds a frame generation function, which can insert a new frame calculated by AI between two real frames to double the number of frames. Combined with the super-resolution function of DLSS 2, AI can reconstruct up to 7/8 display pixels, and the game performance can be up to 4 times higher than that without DLSS.

At present, there are 30 games that support DLSS 3 for the first time, and future new games are bound to support DLSS 3 for the first time, and the total number is still increasing monthly. If you include all the games and apps that support DLSS, then the number will come to more than 280 at once.

We also chose three games that support DLSS 3 for testing. the first is the "Cyberpunk: 2077" ‏‏, where ‏‏ runs its own benchmark under the highest quality super light of ‏‏ 2 ‏‏ K, which, unsurprisingly, has only 37 frames by default, which is barely playable. The quality of DLSS 2 can be up to 67 frames, which belongs to the smooth pass line. On this basis, the number of DLSS 3 frames finally reached 100 frames, and the game experience went up all of a sudden.

Since the next-generation version of "Wizard 3: hunting" has been updated, the configuration requirements have become very scary. Of course, the difference between the picture performance and the host is also very obvious. With the blessing of light pursuit, the fun of watching the scenery has been greatly increased. In our experiments, it is also impossible to run to 60 frames by default, and the performance is similar to that of cyberpunk after turning on DLSS 2, and the tail of 100 frames is finally reached under the dual buff of DLSS 3+DLSS 2.

Finally, the optimization of the better "Plague Legend: Requiem", in the 2K highest picture quality even if not open DLSS, can run to 73 frames, has been very smooth. The quality of turning on DLSS 2 can reach 98 frames, while turning on DLSS 2 + DLSS 3 at the same time can reach 145 frames, which can fully feed the 2K / 144Hz high brush display.

Of course, it is also popular in the circle that ‏‏ DLSS 3 ‏‏ can lead to increased latency and lack of follow-up in playing games. Indeed, the essence of DLSS 3 ‏‏ is that AI generates new frames, and it takes a time to generate frame ‏‏. The improvement of ‏‏ latency has a great impact on competitive games, but the current games that support DLSS 3 are RPG games that do not eat input delay. And when ‏‏ turns on the frame generation function of DLSS 3, NVIDIA Reflex will force it on to minimize the rendering delay caused by the generated frame. ‏‏ We take the Legend of the Plague: Requiem as an example, the delay is only increased by a few milliseconds after opening DLSS 3 + NVIDIA Reflex, which has no effect on the game experience. However, if both DLSS and NVIDIA Reflex are turned off, there will be a significant reduction in latency, but there will also be a large discount on the number of frames and fluency.

Some friends may worry that opening DLSS will have a great impact on the picture quality of the game. For this, we took two screenshots of the game from the next-generation version of "Wizard 3: hunting", which are completely off DLSS state and open DLSS 2+DLSS 3 state at the same time, and then enlarge the two images to compare the details at the same scale, you can see that there is almost no difference after magnification, and the picture quality party can rest assured to open DLSS.

As we mentioned earlier, the power consumption of the RTX 4070 is less than 200W, which is one of its advantages, so how does the power consumption perform in the actual game? Will it exceed 200 watts? We have also counted the actual power consumption performance of several games, all of which are less than 200 watts. Of course, this performance is inseparable from the SM multi-cell stream processor in the new ADA architecture, which can not only improve performance by two times, but also reduce power consumption and kill two birds with one stone.

Creative production ‏ benefits from 12G large graphics memory and powerful CUDA core, RTX 4070 can be used not only for games, but also for creative production. Sotai RTX4070 X-GAMING OC Opal has 5888 powerful CUDA cores and will make some achievements in dealing with creative production and deep learning. At the same time, it ‏‏ ‏‏ can also install ‏‏ NVIDIA Studio driver, ‏‏ has more than 75 creative applications ‏‏ can call ‏‏ NVIDIA CUDA core ‏‏ AI computing power, greatly improving work efficiency.

In the modeling and rendering software, the 5888 ‏‏ CUDA ‏‏ cores of ‏‏ can provide hardware acceleration for ‏‏. At present, almost all modeling software will optimize the GPU of NVIDIA, so it can achieve the coexistence of efficiency, stability and compatibility. For example, in the commonly used rendering tool V-Ray, you can use RTX accelerated ray tracing to achieve high-performance final frame rendering. With the noise reduction feature of AI, GPU can further speed up interactive rendering.

In ‏‏ V-Ray Benchmark ‏‏, Sotai RTX4070 X-GAMING OC Opal scored 1860 points, making it possible to cope with most modeling rendering requirements. ‏

Similarly, there is no problem with RayTracing modeling and rendering, and the running score of the GPU RTX project is 2632.

In the BenchMark that comes with the commonly used renderer tool Octane, the rendering ability of RTX4070 is also very strong. In various tests, its rendering ability is almost equal to the arithmetic power of 4 to 10 GTX 980s, and the progress can be said to be obvious.

In the later part of the video, Sotai RTX4070 X-GAMING OC Opal White is also equipped with the eighth generation NVIDIA NVENC encoder, which supports AV1 coding and dual encoders. AV1 is the next generation video coding technology, which can provide faster video coding and higher quality streaming media transmission performance ‏‏ while occupying the same space. ‏

The trend of AV1 is not only the result of technological advances, but also the pain point of the industry's demand for productivity, which is to significantly compress the size of video files while ensuring that the image quality is almost unaffected.

We also conducted a simple test to export the same video material using two different encodings, H264 and AV1, through the professional version of the clipping software. In the end, the file size encoded by H264 is 159MB, while the file size encoded by AV1 is only 127MB, and the size has been reduced by 21%, but there is no difference in image quality.

In addition, Nvidia also introduced RTX video super-resolution technology, known as RTX Video Super Resolution, for RTX30/40 graphics cards. It can improve the definition of online 1080p video to 4K resolution through GPU's AI calculation, and the principle is a bit like the DLSS technology in the game. At the same time, AI computing power can also intelligently sharpen and strengthen the characteristics and edges of objects and characters. At present, playing online video in mainstream browsers such as Edge and Chrome has supported VSR technology, of course, it needs to occupy certain GPU resources for computing, so it is best not to play 3A games with high graphics card occupation at the same time when watching video with this technology.

In Adobe Premiere Pro, the non-linear editing software most commonly used by creative workers, we turn on GPU Cuda acceleration and then test it with PugetBenchmark. Sotai RTX4070 X-GAMING OC Opal White scored 1532, which can easily cope with complex video clips of 4K or even 8K.

In the special effects production software Adobe After Effects, we also use PugetBenchmark for testing. The final score was 1669, and the performance was quite good.

To sum up, we have also evaluated the Opal white color matching RTX4070Ti before. This series has great personality in the design, and the white graphics card has always been popular in the DIY field. In addition, its price is not high in the big factory graphics card, which is a card with more performance-to-price ratio. In addition, the RTX4070 is also a graphics card with excellent energy consumption, and the power consumption of running 2K games can be controlled within 200W under full load.

From the measured performance, the power consumption of Sotai RTX4070 X-GAMING OC Opabai in the game is not very radical, so the temperature of the grill is relatively low, and of course, the performance release is not weak, so for users who give priority to appearance and mute needs, Sotai RTX4070 X-GAMING OC Opabai is worth a try.
